BINDII'TG- 190151 Application filed Karen 25. was. Serial m. 13,144.

This invention relates to a binding post, and has for its principal object to provide a binding post to which a wire may be very quickly attached or from which the wire me be quickly detached.

i nother important object of the invention is to provide a binding post which w ll. firmly engage the wire so as to prevent its accidental displacement therefrom,

A still further very important object of the invention is to provide a binding post of this nature having an exceedingly simple structure which is easy to manipulam, one which is eficient and reliable, inexpensive to manufacture, strong, durable, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the descripw'tion proceeds, the invention. resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed In the drawing f The figure is an elevation of the binding post embodying the features of our invention showing a portion thereof in section.

Referring to the drawing in detail, it will. be seen that 1 desi ates a panel or any other suitable support t mough which is projected. the post 2 preferably having the end thereof threaded as at 3- in order that nuts 4: may be engaged thereon, one on each side of the panel or support 1, thereby securely locking the post in place. This post is provlded with a transversely extending opening 5 through which may be inserted a wire. The outer end of the post 2 has formed thereon a head 4% 6 of insulating material being cylindrical in formation, as indicated at 7, and provided with a milled flange 8- at its outer end in order that the post may be rotated and screwed through the panel if desired. A slidable member 9 is mounted on the 0st 2 and is substantially cup-shaped in tion including a. cylindrical body 10 adapted to slide over the cylindrical portion 7 of the head 6 and an apertured body 11 through which the post 2 extends. A. flange 12 is mounted on the outer end of the cylindrical body 10 for abutting the flange 8, the eby limiting the outward movement of the 5 idable member 9. A coil spring it is disposed about the post 2 and impinges against the inner end of the head 6 and the bottom 11 of the slidable member 9. The spring 14: is tensioned to normally hold the slidable memher over the opening 5. Thus it will be seen that when the slidable member 9 is moved toward the flange 8 by engaging the fingers on the flange 12 that the wire may be passed through. the opening 5, and then the slidable member may bekreleased for binding against the wire so as to hold it securely in the post against accidental removal.

Having thus described the invention, what we claim as new is 2-- A device of the class described including a post of cylindrical formation having an intermediately disposed diametrically extending opening formed therein for receiving a wire, a head of insulating material formed on one end of the post a distance "from the opening and including a cylindrical body and a milled flange of greater diameter than the body, a cup-shaped slide member including a cylindrical body slidable over the first-mentioned cylindrical body and an apertured bottom through which the post extends, an annular flange formed on the u per end of the cylindrical body of the sli e member and projecting outwardly, and a. coil spring disposed about the post and impinged against the bottom of the slide member and the adjacent end of the head, the flange on the slide member being abuttable with the flange on the head to prevent injury to the spring.

" In testimony whereof we aflix. our signatunes.
